First, we will start with normal insert statements. Then we will go ahead with inserting data from existing tables in the SQL Server Database.
“Table Joins” are useful for bringing data together from different tables based on their database relations. First, we will see how the join operates between tables. Then we will test the Order of Execution when Join and where condition both lies. Finally, we will move our exploration to Importance of the Join order.
